Abstract
With the increase in the size of storage tanks, the larger spans of the tanks place higher demands on the safety of the shell structure. This study improves the traditional single-layer spherical shell structure used in oil tanks by adding prestressed cables to the original Kiewitt reticulated shell, creating a new type of prestressed shell structure. The prestressed cables help balance the internal forces in the shell members, significantly improving its overall ability to withstand earthquakes. This paper carefully examines how the prestressed shell affects the earthquake resistance of the Kiewitt reticulated shell, considering the support provided by the lower tank to the upper shell. The earthquake performance of the shell is analyzed using a time-based method, and the study explores how different levels of prestress affect the shell's response to earthquakes. Additionally, the paper compares how the shell behaves under steady and dynamic loads, focusing on how the prestressed shell deforms during strong earthquakes.
